To avoid these which difficulties, we now employ a train of gearing Figure 1 represents a side view of a printer for joining the escapement or step-by-step of that class in which messages are printed wheel with the paper tube in such manner as upon sheets of paper first made into tube to positively convey to the tube the movements of the wheel both for circumferential and axial feed.

In Fig. 7 is shown a sheet of paper formed into a tube T, whose overlapping edges, when pasted together, are perforated with a line of holes h it, into which the teeth of a small spurwheel are connected, whereby the tube may be given circumferential feed a step at a time for each succeeding letter and axially from line to line in forming the page. The train of gearing for connecting the escapement-wheel with the paper tube is represented in Figs. 1, 2, 3, 4, 5, ti,and 8. In this connection, j is a ratchet-wheel upon whose shaft is rigidly fixed a wheel i, which meshes with a wheel 7r, upon whose shaft is also placed a larger wheel is, gearing with a large ringwheel Z, which surrounds the tubular support a, and which is supported upon friction-rollers m m n a. The ring-wheel [is of a diameter considerably in excess of that of the supporting-tube a and sutiieiently greater to enable the mounting of a small spur-wheel f upon or within the ri11g-wheel in such relation that the teeth of f may project through the holes in the paper tube into circumferential or diagonal grooves formed in the periphery of the tubular support. the escapement or step-bystep wheelj is permitted to rotate its movement is imparted by way of spur-wheels i k 7.2 l to the small spurwheel f, the teeth of which projecting through the holes of the paper tube carry the latter circumferentially from one letter position to the next around the stationary tubu lar support. This train of gear is subject to a continuous propulsive action from a motor 6, Fig. 1, gearing with a shaft d, which in turn, by a beveled gearfg, imparts a winding tendency to one end of a coiled spring, the other end of which is connected with the shaft upon which the spur-wheel i is mounted, and by this means with each movement of the eseapement-pallets which control wheel j the train of wheels connecting j with the wheel meshing with the paper tube is given a step of rotation. The teeth upon wheel j, with the exception of a blank portion, are equally spaced over its periphery and are of a number equal to the characters in each line of the printed message, while that portion of the periphery upon which no teeth appear is of sufficient length to permit an abnormallylong step of rotation, a step usually made equal to six or seven of the shorter steps and it is by this means that the paper tube is at a single step of the escapement permitted to rotate a distance representing the two margins of the printed page. The escapement just referred to is operated by magnet M and an armature R, which is pivoted upon a shaft R, upon which is carried a suitable bracket and pawls -t and 5, the pawl 5 being fixed with reference to its supportingbraeket, whileiis movable around an axis (5. 3y this means as armature R is attracted pawl 5 will be drawn into a space between teeth Thus as p of the ratchet-wheel, while pawl -1- will be disengaged. This action, however, permits the escapementwheel to move only a very small distance, while at the same time pawl t is disconnected from the wheel and by means of a sprin 21 is caused to move backward in a direction opposite to the rotation of the escapement-wheel and into such a position that upon the retraction of armature R it will drop into the next notch just before pawl 5 is disconnected. In other words, just before disengagement of pawl 5 pawl 4 will be thrown into that cavity of the wheel next back of the one which pawl 5 had left, thus leaving the wheel, under the action of the propelling motor, free to rotate an additional step.

Although we desire to limit ourselves to no specific form of ringwheel we have shown apreferred construction in Figs. 2, i, and 8, in which are represented a ring having horizontal projecting edges or flanges .9 and a surrounding series of spur-teeth. By this means wheell is easily mounted and retained in position meshing with spur-wheel 7t, since by this construction friction rollers or guides at m a 11, having central grooves, may support the wheel both circumferentially and axially. The peripheries of these rollers serve as guides and supports for the flanges s .5, while their central groove affords a passage-way for the spur-teeth of the wheel, the sides of said grooves atthe same time serving to hold said wheel in an accurate axial position. Upon the inner periphery of the wheel Z is affixed a bracket or shoe, (particularly shown in Figs. 5 and 6,) within which is pivoted the small spur-wheel f, which meshes with the holes in the paper tube. In Figs. 5 and (5 is shown a bracket-piece a, joined to b by means of a yoke 0, having arms 1 and 2, within which is pivoted a shaft g, carrying the spur-wheel f, and to secure the bracket to the wheel Z the arms a b are preferably provided with scyew-holes (Z, by means of which its convex surface maybe bolted to the inner peri 'ihery of l, as shown in Fig. 8.

Preparatory to the printing of a message spur-wheel f is brought into a pred QlCllTll11G(l position with reference to the tubular support, and while f is in this position the tubular blank is pushed along the support until the first holes in the lap of the tube are brought into mesh with its teeth. The particular means by which this is accomplished are shown in Fig. 3, .in which is represented. a small slot 11., cut into the tube lengthwise slightly at one side of a central line. If wheel f is brought into the plane of the slot 11/, oh-

viously it may be rotated and the paper tube may be thrust forward, since the teeth of 1" will find a clearance in the slot and will at the same time mesh with the holes 7L 7:. of the tube T.

To accomplish the circumferential feed of the paper tube, wheel f is swept circu1nferentially around the tubular support a, its

teeth at the time being stationary with reference to its own axis, they being held Within the circumferential grooves r s t of the tubular support, as shown in Figs. 3 and 6. At the end of each line of the message, however, the teeth of the wheel are brought to the inclined grooves 12 w an, and by this means wheel f is given a rotation equal to the angular space covered by two of its teeth and a distance equal to that from one line to the next, and it is by this means that the paper, while given a circumferential rotation representing the two margins of the page, is also moved axially a sufficient distance for a new line. Thus it is seen that the spur-wheel f, while bodily carried by the ring-wheel Z, has its teeth projecting through the holes in the lap of the paper tube T into the circumferential grooves in the tubular support and that the wheel f is held stationary upon its own axis during the printing of a line, while thereafter it is rotated sufficiently to move the paper for a new line while the teeth of the wheel are moving through the inclined grooves 11 10 av. To the end, however, that the teeth of wheel 9 may move freely past ,the slot u the inclined grooves 41 w as are terminated a short distance at the right of the slot, whereby the teeth of the wheel in normal operation after passing the inclined grooves must find their normal position within the planes of the circumferential grooves before reaching the position of the slot. To furtherinsure against the catching of the teeth of wheel f in passing slot to, the wheel is provided with a small dogging check-wheel q, having concaved or notched sides within which the curved end of a spring or dog 19 may press. By this means the teeth of f can have but one normal position, as shown in Fig. 6, a position in which they are certain to enter the circumferential grooves after passing the slot it, while printing from one line to the next or at the beginning of the first line of a message.

Cam-wheel q and its spring p are particularly necessary in determining the position of the teeth of the wheel when a blank for a new message is first inserted. lVithout some such arrangement the teeth of the wheel would be left in any angular position, so that upon the first operation 'of the feeding device they might be caught by the ends of the ridges between the circumferential grooves of the tube.

In carrying out our invention we employ manual means for connecting and disconnecting the escapement-wheel from its pallets, whereby at the end of a message, if only part of a line has been printed, the escapementwheel and its accompanying gear mayimmediately return to a zero position. This apparatus we have particularly shown in Figs. 1 and 4c, in which on is a rod carrying a handbutton at one end and an arm near the other, engaging in a groove 8, formed in the hub or support of the escapement-wheel j. Another part of the hub, carrying the escapementwheel is provided with a slot within which slides a pin 10, connected to the drivingshaft, while upon an auxiliary disk fastened to the escapement-wheel j is a tooth 7, the end of which in normal rotation clears a fixed stop 22, but which, when rod m is pulled to the left, is brought into the path of such fixed stop, whereby as the escapement-wheel is disengaged from its pallets stop '7 will be put into a unison position; that is to say, in such a position that wheel f will at the time be in the plane of slot to.

The conditions essential in operating the escapement are that its wheel shall not rotate at the time of actuating the press mechanism or when armature R is attracted by magnet M. It should only operate when armature R is moving into a back position or after printing has taken place. A further condition is that the escape-wheel at the end of a message, when it is desired to let the apparatus or train-run to zero, shall be disconnected from the fixed pallet of the escapement and not from the movable pallet. If the wheel were disconnected from the movable pallet and not from the fixed one, the reengagement would be with the movable pallet, and thereby one false step of rotation would take place in the escapement, thereby causing a disarrangement of the lines of the printed message. To avoid this difficulty, the escapement and its magnet have been arranged as shown in Figs. 4 and 8, in which, for unison disengagement, the escape-wheel is moved to the left, assuming at the same time the armature R to be attracted so that stationary pawl 5 would normally be in a position to arrest the teeth of the wheel. Upon disengagement the wheel is pulled to the left of 5, leaving it free to rotate, and by this means it is apparent thatwhen rod m is thrust to the right the teeth of the wheel will be pushed back over the stationary tooth of the escapement, thus at the beginning of a new line leaving the escapement-wheel in the exact position it would have occupied if disengagement had not taken place.

If a message were completed after having printed only a few characters upon a line and the escapement wheel were disconnected from its pallets, the feeding-train would move to unison position with great rapidity. To avoid injuring the apparatus by unnecessary blows, a train of gearing carrying a fly or fan has been provided, as shown in Figs. 1 and 4:, which may be connected to the shaft of the escapement-wheel at the time the latter is disconnected from its pallets. This organization has been specifically described and claimed in another application and affords no part of the present invention except as it is a part of the combination of our new positive-feed arrangement. As here shown, a clutch 11 and 12 is normally disconnected, the free portion thereof being connected to fan 13. Upon pulling m to the left to disengage the escapement-wheel from its pallet 11 and 12 of the fly-clutch will be engaged,

thus joining the fly with the escapementtrain.

As shown in former patents, a rubber band is carried within the tubular support between the type-wheel and the press-hammer. In such instances, however, the rubber band is rotated by the action of a wheel within the tubular support driven by a friction feeding device acting from without the tube; but as the friction feeding device is now omitted it is necessary to employ other means for actuating the rubber band. As shown in Figs. 4and 8, 19 is such a rubber band, it being carried around two upper rollers 20 and a single lower roller 18, placed upon a shaft 17, also provided with a ratchet-wheel 16, with whose teeth an arm 15, attached to the press-lever, engages. 13 y this means, with each movement of arm P, the band 19 is given a slight movement, and during continued operation its entire length is repeatedly brought opposite the small aperture 21, through which the press acts upon the type.

The tubular support a is made in three sections w w 7 as shown in Figs. 3 and 4. Sections 10 and y are preferably brass tubing of a circumference slightly less than the length of the paper sheet of which the tubes are formed, while the middle section 00 is of iron, whose shell is thicker than that of w and q and particularly at that part within which the circumferential and inclined grooves for controlling the action of spur-wheel f are cut. As shown in Figs. 3 and 4, the tube is provided with two joints .2 and 2. detail of this construction is shown in Fig. 3, which consists of a small block of metal having a cylindrical and convex surface within which the diagonal grooves o in 5a are cut. Corresponding with such block the tube-section-a: is provided with an aperture, and within this aperture is closely fitted the block, all of which forms the arrangement of the circumferential and inclined slots, as shown in Fig. 3.
